I just don't like the weapon (im)balance in WAW.
Bolt action rifles take 2-3 hits to kill in regular play, during which time someone with a semi/auto will fill you full of holes.
In HC they're 1 hit kills, but then so are 99% of the other guns too so you still don't gain anything.

Wish they'd make the bolt-actions like they were in the original CoD: Chest or higher is a one-hit kill
